Water Retention
Porous Biochar may help retain moisture in the root zone, particularly in fast-draining or degraded soils.
Practical Biochar for Canadian agriculture
Biochar for Farms & Livestock
Biochar for farms supports long-term soil improvement, greenhouse production, nutrient management and practical manure and bedding systems. The right approach depends on your soil, crop, livestock operation and project scale.
01 / Farmers
Biochar for Agriculture & Farm Soil
Biochar is a stable, porous carbon amendment. When it is matched to the soil and combined with compost, managed manure or fertilizer, it can become part of a long-term soil program for fields, greenhouses, orchards and other growing operations.
Where it fits
A Long-Term Investment in Better Farm Soil
- Crop fieldsAdds long-lasting carbon structure that helps retain water and nutrients, supports soil biology and keeps more applied fertility within the active root zone.
- GreenhousesHelps buffer moisture and nutrients in intensively managed growing media, supporting a more consistent root-zone environment between irrigation and feeding cycles.
- Depleted or low-organic-matter soilsAdds stable carbon, nutrient-exchange surfaces and microbial habitat—helping compost and fertilizer rebuild soil function instead of acting as short-lived inputs.
- Sandy soilsIts sponge-like pore network helps retain water and dissolved nutrients, reducing rapid movement beyond roots and keeping more fertilizer available to plants.
- Orchards and similar operationsCreates durable moisture, nutrient and microbial habitat around perennial root zones, supporting more resilient soil between irrigation and fertilizer applications.
Potential benefits
What Biochar May Add to a Soil Program
Nutrient Retention
Its surfaces can interact with nutrients, helping reduce leaching and keep more value in the managed soil system.
Cation Exchange Capacity
Biochar can contribute exchange sites that help soil hold positively charged nutrients such as calcium, magnesium and potassium.
Microbial Habitat
Pores provide protected microsites where beneficial soil microorganisms can interact with moisture, nutrients and roots.
Stable Carbon
Biochar adds a durable carbon structure that remains in soil far longer than fresh organic matter.
Long-Term Improvement
Depending on the Biochar and starting soil, it may help improve acidic or degraded soils as part of a broader management plan.
Research behind the benefits
Long-Term Soil and Water Findings
Benefits persisted for more than a decade
A long-term field study reported that one Biochar application continued to influence soil after more than 10 years, including higher soil pH, cation exchange capacity, retained nutrients and soil organic carbon. Crop responses and the most effective rate varied, reinforcing the need to match Biochar to the soil and crop.
Read the university research summary ↗Water retention improved in a degraded soil study
In a six-year study of degraded calcareous soil, one-time organic amendments increased water retention. The treatment combining 1% Biochar with 2% manure produced the strongest and most consistent plant-available water result among the tested treatments.
View the USDA study record ↗Important: Results vary with soil texture and pH, Biochar feedstock and production conditions, particle size, crop, climate, fertility program and application rate. Biochar should not be presented as a guaranteed yield increase. Start with the soil and the production goal.
02 / Livestock
Biochar for Livestock, Bedding & Manure Management
Across cattle barns, poultry coops, goat and sheep pens, and other livestock facilities, Biochar can be added to bedding and manure-management systems to help manage moisture, ammonia-related odour and nitrogen. After use, the Biochar-enriched bedding and manure can be properly composted and returned to the farm as a valuable soil amendment.
Practical livestock uses
Cleaner Bedding, Better Manure & More Retained Nitrogen
- Chicken coops and poultry beddingDistribute an appropriate grade through managed bedding or targeted high-moisture areas as part of normal litter care.
- Barns and livestock pensUse Biochar alongside ventilation, drainage, dry bedding, cleaning and routine manure management—not in place of them.
- Manure pilesBlend Biochar evenly with manure and bedding rather than applying one thick, isolated layer.
- Manure compostingAdd Biochar during pile construction to support ammonia management and retain more nitrogen in the finished material.
- Bedding and organic wasteMove used Biochar-containing material into a properly managed composting process, then use the finished amendment according to its analysis and intended crop.

From Odour Control to Soil Amendment
Manage Moisture & Odour
Biochar can be incorporated into bedding and manure systems where moisture and odour require active management.
Reduce Ammonia Losses
Biochar can reduce ammonia emissions and improve nitrogen retention in well-managed bedding and manure systems—helping control ammonia-related odour while keeping more nitrogen in the material for composting.
Improve the Compost Stream
Used bedding and manure can be composted with Biochar to create a more valuable soil amendment while recycling farm nutrients.
Research behind the benefits
Manure, Ammonia & Nitrogen Findings
Compost mixtures can retain more nitrogen
Cornell reports that adding Biochar during composting can reduce ammonia and nitrogen losses, improve compost quality and help reduce odour pollution from manure and organic waste. Performance depends on the materials and composting process.
Read the Cornell research summary ↗Lower ammonia emissions were measured during composting
Controlled poultry-litter composting studies published in Waste Management and the Journal of Environmental Quality found lower ammonia losses and better nitrogen retention in specific Biochar treatments. These findings support Biochar as a manure-composting amendment; they do not guarantee identical results in every facility.
